DETAILED DESCRIPTION

It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents.

The following brief definition of terms shall apply throughout the application:

The term “comprising” means including but not limited to, and should be interpreted in the manner it is typically used in the patent context;

The phrases “in one embodiment,” “according to one embodiment,” and the like generally mean that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present invention, and may be included in more than one embodiment of the present invention (importantly, such phrases do not necessarily refer to the same embodiment);

If the specification describes something as “exemplary” or an “example,” it should be understood that refers to a non-exclusive example;

The terms “about” or “approximately” or the like, when used with a number, may mean that specific number, or alternatively, a range in proximity to the specific number, as understood by persons of skill in the art field (for example, ±10%); and

If the specification states a component or feature “may,” “can,” “could,” “should,” “would,” “preferably,” “possibly,” “typically,” “optionally,” “for example,” “often,” or “might” (or other such language) be included or have a characteristic, that particular component or feature is not required to be included or to have the characteristic. Such component or feature may be optionally included in some embodiments, or it may be excluded.

Embodiments of the disclosure include systems, apparatuses, and methods of assembling and/or using a slide with a play structure. The slide may comprise multiple configurations for storage/shipping/transport (e.g., before assembly) and for use (e.g., when assembled).

Typically slides may be bulky with respect to the space needed for storage and/or shipping and handling, and/or the slide can comprise many small pieces which require substantial time to assemble. Where a slide structure may require less space or fewer pieces to assemble, the result is often a sacrifice of the decorative touches that both functionally and aesthetically enhance the playtime experience. To improve shipping availability and ease of assembly of the slide, it may be desired to fold and/or collapse the slide to fit within a particular size of box (e.g. reducing the bulkiness of the slide into a flatter shape). The disclosed foldable slide embodiments typically have a fold feature interface between the side rails and slide surface, which decreases the space needed during storage, shipping, and/or stocking at retail stores.

FIG. 1 illustrates an exemplary play structure 10 comprising a foldable slide 100 (set up for use, e.g. assembled) attached to a main structure. The foldable slide 100 may extend from a second (or higher) story (or floor) of the structure to the ground.

FIG. 2 illustrates the foldable slide 100 in a first (folded) position or configuration. FIG. 3 illustrates the foldable slide 100 in a second (unfolded) position or configuration. The slide 100 may comprise two side rails 102 which may be mirrored and matching one another. The slide 100 may comprise a sliding surface 110 positioned between and attached to the two side rails 102. In some embodiments, the sliding surface 110 may be attached to the two side rails via one or more hinges 120 (e.g. configured to allow folding of the side rails with respect to the slide surface, in order to provide the two configurations).

The side rails 102 may comprise one or more shaped portions configured to provide support and/or connection to other elements. For example, the side rails 102 may comprise panels 104 configured to extend beyond the sliding surface 110 and/or angled to connect to a play structure. The side rails 102 may comprise legs 106 configured to support the slide 100 and contact the ground. The legs 106 may be configured to extend beyond the sliding surface 110 and/or be angled to support the bottom of the slide above ground level. In some embodiments, the side rails 102 may comprise raised portions 108 near the top of the sliding surface 110 (e.g., the furthest portion of the slide from the ground when the slide is installed onto a play structure) for example, to prevent falls off of the sliding surface 110. The main portion of the side rails (e.g. between the panel 104 and the leg 106) typically would be configured to extend longitudinally along the length of the slide, and for example might have a bottom surface similar to the slide contours.

In some embodiments, the sliding surface 110 may comprise one or more curved portions. For example, the sliding surface 110 may comprise a top curved portion 112 configured to provide a connection between the play structure (e.g., a floor of the play structure) and the sliding surface 110. In some embodiments, the top curved portion 112 may comprise a curve that approximately matches the shape of the panels 104. As another example, the sliding surface 110 may comprise a bottom curved portion 114 configured to curve toward the ground from the sliding surface 110 when the slide 100 is installed for use. In some embodiments, the bottom curved portion 114 may comprise a curve that approximately matches the shape/curve of the legs 106 (at least for a portion). In some embodiments (not shown), the main portion of the slide surface could include additional curvature based on slide design, or it could be substantially straight/flat as shown in FIGS. 3-4.

The slide 100 may comprise one or more (or a plurality) of hinges 120 configured to allow the side rails 102 to rotate/fold with respect to the sliding surface 110. For example, the side rails 102 may be moved from a first position (shown in FIG. 2) to a second position (shown in FIG. 3) via movement of the hinges 120.

FIG. 4 illustrates a front view of the foldable slide 100 in the second (unfolded) position, as described above. FIG. 5 illustrates a back view of the foldable slide 100 in the second (unfolded) position, as described above. As shown in FIG. 5, the slide may comprise one or more braces 130 positioned along and/or be attached to the backside of the sliding surface 110 (although in other embodiments, the support for the slide surface (e.g. as provided by the braces in FIG. 5) might be integral to the slide surface itself). In some embodiments, the hinges 120 may be incorporated into (and/or attached to) the one or more braces 130. The braces 130 may be configured to support the sliding surface 110 during use, to prevent stress that might break, bend, or overly flex the sliding surface 110. Although the hinges 120 are shown as aligned with and attached to the braces 130, the hinges 120 may also function independent of any braces. As an example, a sliding surface 110 may be used that does not require braces (e.g. the sliding surface itself is sufficiently strong to not need additional support and/or the support might be integrally formed as part of the slide surface), in which case the hinges would not be aligned with or attached to braces (but for example might directly attach to the slide surface).

FIG. 6 illustrates a detailed view of such an exemplary hinge 120 in the first (folded) position. FIG. 7 illustrates a detailed view of the hinge 120 in the second (unfolded) position. The hinge 120 may be attached to the side rail 102 and the sliding surface 110 and/or the brace 130. In some embodiments, the hinge 120 may comprise a bolt 132 configured to fit within an opening 134 of the brace 130. In some embodiments, the hinge 120 may comprise a first hinge portion 124 and a second hinge portion 126 which may be connected via a pivot portion 128. In some embodiments, the hinge 120 may comprise one or more through-holes 125 and 127 configured to allow a fastener (e.g. bolt) to pass through the through-holes. In some embodiments, the first hinge portion 124 may comprise a first through-hole 125 and the second hinge portion 126 may comprise a second through-hole 127. In the second position, the bolt 132 (or fastener) may pass through the brace 130, the sliding surface 110, the through-hole 127, and the through-hole 125 to fasten with the side rail 102 for assembly of the slide (for example, with full assembly requiring this type of fixing of the side rail in the second position with respect to the slide surface for all such hinges).

In some embodiments, the hinge 120 may be molded into the side rail 102 and/or slide surface/braces. In some embodiments, the hinge 120 may be attached to the side rail 102 and/or the sliding surface 110 via screws. In some embodiments, the side rail may comprise a lip 103 configured to extend beyond the sliding surface 110. In some embodiments, the lip 103 may align with the brace 130 in the second position (shown in FIG. 7).

As discussed above, in some embodiments, the corner joints/hinges (for example of a foldable slide structure) could employ/comprise a pivotal attachment element/hinge, which might be configured to retain a fastener and self-align the fastener for lock of the related corner panels when the slide is unfolded. Details of such an exemplary assembly device and/or pivotal attachment element are set forth below and may relate to the exemplary slide structures shown in FIGS. 1-7 for example.

Referring to FIG. 8, a typical planar support element 2100 is shown, wherein the planar support element 2100 may be a panel, a wall panel, a board, flat sheet, rod, substrate with leading edge or surface (or thickness), wood panel, glass panel, plastic panel, metal panel, sheet metal, etc. As used herein, panel and planar support elements may be used interchangeably and are intended to broadly cover these and similar elements. In some embodiments, the planar support element 2100 may be similar to one or more of the side rails 102, sliding surface 110, and/or braces 130 described above.

The planar support element 2100 may comprise a plurality of edges, ends, surfaces, or faces, which may be designated for identification purposes as a first edge 2101, a second edge 2102, a third edge 2103, a fourth edge 2104, a first face 2105, and a second face 2106. In the embodiment shown in FIG. 8, the edges 2101, 2102, 2103, and 2104 may comprise a narrower width than the faces 2105 and 2106. In other words, the edges 2101, 2102, 2103, and 2104 may form a narrow border surrounding the two faces 2105 and 2106, wherein the faces 2105 and 2106 may be parallel to one another. As shown in FIG. 8, the edges and faces may be rectangular in shape, but in other embodiments, the edges and/or faces may comprise other shapes depending on the purpose and function of the planar support element 2100.

In some embodiments, one or more planar support element 2100 may be substantially planar (e.g. not entirely planar), wherein the two faces 2105 and 2106 may be substantially planar in shape, with the edges 2101, 2102, 2103, 2104 surround the two planes. In some embodiments, the planar support element 2100 may comprise other features or elements incorporated and/or built onto the planar shape, which may protrude from the substantially planar shape (but regardless, these substantially planar support elements are intended to be included within the term “planar support element” as used herein).

FIG. 9 illustrates an exemplary pivotal attachment element 2200 according to an embodiment of the disclosure. The pivotal attachment element 2200 may comprise a hinge, a joint, a pivot, or another similar pivotal attachment element. In some embodiments, the hinge 120 described above (for foldably attaching the side rail to the slide surface/brace for a foldable slide) may comprise a pivotal attachment element 2200 as described herein.

In some embodiments, the pivotal attachment element 2200 may comprise a first hinge portion 2204 and a second hinge portion 2206 which may be connected via a pivot portion 2202, wherein the pivot portion 2202 may allow the first hinge portion 2204 and the second hinge portion 2206 to pivot with respect to one another about the pivot portion 2202.

In some embodiments, the pivot portion 2202 may comprise a thinned section between the first hinge portion 2204 and the second hinge portion 2206, wherein the thinned material allows for the material to bend when the first hinge portion 2204 and the second hinge portion 2206 are moved relative to one another. In some embodiments, the pivotal attachment element 2200 may comprise a living hinge, for example comprising thin, flexible webs (within the pivot portion 2202) that connect two relatively rigid adjacent wall sections (i.e., the first hinge portion 2204 and second hinge portion 2206). In some embodiments, the pivot portion 2202 may comprise a material with increased flexibility with respect to the rest of the pivotal attachment element 2200. In some embodiments, the pivot portion 2202 may comprise a material with decreased tensile strength with respect to the rest of the pivotal attachment element 2200. Typically, the pivot portion may provide a range of motion of approximately 0-90° and/or 0-180°, for example.

In some embodiments, the pivotal attachment element 2200 may be injection molded, extruded, and/or produced via machining or stamping. In some embodiments, the pivotal attachment element 2200 may comprise a plastic material, such as polypropylene. In some embodiments, the pivotal attachment element 2200 may comprise any flexible material including olefins, vinyl, and other plastics. In some embodiments, the pivotal attachment element 2200 may comprise metal, wood, and/or plastic. In some embodiments, the pivotal attachment element 2200 may comprise a single continuous element (e.g., with hinge portions and a pivot portion), while in other embodiments, the pivotal attachment element 2200 may comprise two separate hinge portions connected by a pivot portions, wherein the portions are separate elements attached to one another, such as by a pin.

In some embodiments, the pivotal attachment element 2200 may function as a temporary alignment feature, and therefore the material of the pivotal attachment element 2200 may comprise an overall tensile strength less than a typical hinge (e.g. permanent), as the pivotal attachment element 2200 will not be used repeatedly throughout the life of the final structure that is formed by the pivotal attachment element 2200 and the planar support elements. For example, the pivotal attachment element may not be intended to serve as the primary structure attachment between the two planar support elements after assembly, since the fastener is intended to serve that role, so the pivotal attachment element can be a less durable, temporary support (e.g., merely for use during assembly and/or for use after assembly only in conjunction with primary interlocking support of the fastener). In some embodiments, the pivotal attachment element 2200 may comprise a temporary and/or degradable material, such as cardboard.

The pivotal attachment element 2200 may comprise one or more through-holes 2214, 2216 configured to allow a fastener to pass through the through-holes 2214, 2216. In some embodiments, the first hinge portion 2204 may comprise a first through-hole 2214 and the second hinge portion 2206 may comprise a second through-hole 2216. When the pivotal attachment element 2200 is folded (e.g., when the first hinge portion 2204 is rotated about the pivot portion 2202 toward the second hinge portion 2206) such that the first hinge portion 2204 contacts the second hinge portion 2206 (e.g. the second position), the through-holes 2214 and 2216 may be aligned such that a fastener may pass through both through-holes 2214 and 2216. In some embodiments, the first hinge portion 2204 and/or the second hinge portion 2206 may comprise attachment holes 2210 configured to allow for one or more fasteners to attach the pivotal attachment element 2200 to one or more planar support elements. In another embodiment, the pivotal attachment element 2200 may be attached to one or more planar support elements without the use of screws or the attachment holes 2210.

FIGS. 10A-10C illustrate another embodiment of a pivotal attachment element 2200, wherein the second through-hole 2216 may comprise a retaining feature 2218 configured to retain a fastener 2300 (e.g., during transport of the structure comprising the pivotal attachment element and/or planar support elements, for example before fixed assembly of the structure and/or permanent attachment of the planar support elements by the fastener), and configured to align the fastener 2300 during assembly of the structure. In some embodiments, the retaining feature 2218 may comprise a specific shape configured to hold a fastener 2300 in place within the through-hole 2216. In some embodiments, the second through-hole 2216 may be configured and/or shaped to at least temporarily retain the corresponding fastener 2300, which may include one or more of the following: a securing element, a screw, a bolt, a bar, a rod, a pin, or another similar fastening element. In some embodiments, the fastener 2300 may comprise a lag screw, a wood screw, or a machine bolt. FIG. 10A shows the pivotal attachment element 2200 configured with an integral retaining feature (e.g. in the second through-hole 2216), while FIGS. 10B-10C show a fastener included therein. In FIG. 10C, the retaining feature may comprise a separate disc 2302 or other retaining element attached to the fastener 2300 once it passes through the second through-hole 2216 configured to prevent the fastener 2300 from exiting the second through-hole 2216. Such a separate retaining element could be used alone or in conjunction with an integrated retaining feature (such as the tabs, etc.).

In the embodiment of FIGS. 10A-10C, the retaining feature 2218 of the second through-hole 2216 (e.g. of the second hinge portion 2206) may comprise one or more tabs configured to extend into the opening of the through-hole 2216 to contact and therefore retain a fastener 2300. In some embodiments, the second through-hole 2216 may comprise one or more of the following: tabs, teeth, zig-zag teeth, cross-slits, and/or another similar retaining shape. In some embodiments, the retaining feature 2218 may comprise a material with flexibility to allow the retaining feature 2218 to retain a fastener 2300 while still allowing the fastener 2300 to be moved into/out of the through-hole 2216 (e.g., during assembly, as moving from the second to the third position).

Referring to FIG. 11, the retaining feature may comprise a separate disc 2302 or other retaining element attached to the fastener 2300 once it passes through the second through-hole 2216 configured to prevent the fastener 2300 from exiting the second through-hole 2216. Such a separate retaining element could be used alone or in conjunction with an integrated retaining feature (such as the tabs, etc.). In the embodiment shown in FIG. 11, the fastener 2300 may comprise a head 2310, wherein the head 2310 and the disc 2302 may prevent the fastener 2300 from exiting the second through-hole 2216.

Referring to FIG. 12, in some embodiments, the pivotal attachment element 2200 may also comprise a mating fastener locking element 2320 (such as a nut), corresponding to the fastener 2300. This mating fastener locking element 2320 may be integrated to the first hinge portion 2204, for example with a centerline matching that of the first through-hole 2214.

FIGS. 13A-13B show an exemplary structure (e.g. formed of two planar support elements joined by a pivotal attachment element, for example as described above), and its first and second positions or configurations. FIG. 13A illustrates a first position or configuration (e.g., folded flat for storage and/or transport, for example within a box) of a first planar support element 2400 and a second planar support element 2410. The first planar support element 2400 and the second planar support element 2310 may be used to build a structure and may be shipped to a final customer and/or stored in this first position (e.g., within a box) before being assembled into the structure. The first planar support element 2400 may comprise a first edge 2401, a second edge 2402, a third edge 2403, a fourth edge 2404, a first face 2405, and a second face 2406. The second planar support element 2410 may comprise a first edge 2411, a second edge 2412, a third edge 2413, a fourth edge 2414, a first face 2415, and a second face 2416. While FIG. 13A illustrates only two panels, it should be understood that in some embodiments, the two panels would be attached with hinges to one or more additional panels (e.g., part of foldable slide) and/or might be attached with multiple hinges and/or extended/larger hinges.

The first position shown in FIG. 13A may be a compact position for transport of the planar support elements 2400 and 2410 (e.g., within a box, with planar support elements folded up for compact storage to reduce box size). In the embodiment shown in FIG. 13A, the planar support elements 2400 and 2410 may be parallel and contacting one another in the first position. For example, a second face 2406 of the first planar support element 2400 may be parallel to and in contact with a first face 2415 of the second planar support element 2400. In some embodiments, the second face 2406 may be an inner face, and the first face 2415 may also be an inner face, wherein the inner face of each of the planar support elements may be in contact in the first position. In some embodiments, a portion of the second planar support element 2410 may extend past the first edge 2401 of the first planar support element 2400. For example, in FIG. 13A, the extending portion of the second planar support element might correspond with and/or approximate the second hinge portion dimension (e.g. width).

FIG. 13A illustrates the pivotal attachment element 2200 as attached to a first planar support element 2400 and a second planar support element 2410 in the first position. In the embodiment shown in FIG. 13A, the first hinge portion 2204 may be attached to a first edge 2401 of the first planar support element 2400, and the second hinge portion 2206 may be attached to a first face 2415 of the second planar support element 2410 (in proximity to edge 2411 of the second planar support element 2410). In some embodiments the first hinge portion 2204 and the second hinge portion 2206 may be attached to the first planar support element 2400 and the second planar support element 2410 via screws, snaps, adhesive, tapes, grooves, ridges, slots (e.g., to slide the hinge portions into), and/or a gib and slide assembly. In some embodiments, the first hinge portion 2204 and/or the second hinge portion 2206 may be recessed into the material of the first planar support element 2400 and/or the second planar support element 2410 (e.g., so that their outer surface is approximately flush with the surface into which they are each recessed). In some embodiments, the first hinge portion 2204 and the second hinge portion 2206 may be directly incorporated into the material of the first planar support element 2400 and the second planar support element 2410, for example, if the first planar support element 2400 and the second planar support element 2410 comprise a molded plastic material, and the first hinge portion 2204 and the second hinge portion 2206 are molded into the first planar support element 2400 and the second planar support element 2410.

Also, in the embodiment shown in FIG. 13A, the first hinge portion 2204 and the second hinge portion 2206 may be perpendicular to one another, about the central pivot portion 2202 (shown in FIG. 9) in the first position. The first position (shown in FIG. 13A) may allow the two planar support elements 2400 and 2410 to lay flat against one another for transport purposes, where the pivotal attachment element 2200 may attach the two planar elements 2400 and 2410 while allowing them to lay flat. Once a customer wishes to assemble a structure that includes the two planar support elements 2400 and 2410, they may be move from the first position to a second position or configuration (e.g., for assembly of a corner of a structure).

In the embodiment shown in FIG. 13A, the second planar support element 2410 may comprise a receiving hole 2420 that extends through the thickness of the second planar support element 2410, wherein the receiving hole 2420 is configured to allow a fastener to fit through the receiving hole 2420 and into the pivotal attachment element 2200. Typically, the fastener (sized to fit through the receiving hole 2420, the holes in the hinge and the hole in the first planar support element) would be located and retained within the second planar support element in the first position (e.g. before assembly).

The second planar support element may comprise a receiving hole, wherein the receiving hole may comprise a counter-drilled (or counter-bore, or counter-sink) section configured to fit the shape of the fastener and allow the fastener to be completely recessed within the thickness of the second planar support element (e.g., in the first and/or second positions).

FIG. 13B illustrates a second position (e.g. unfolded and/or assembled) of the two planar support elements 2400 and 2410. In the embodiment shown in FIG. 13B, the first planar support element 2400 and the second planar support element 2410 may be rotated (e.g. unfolded) with respect to one another about the pivotal attachment element 2200, from the first position to the second position. In some embodiments, the two planar support elements 2400 and 2410 may create a corner element or section of a structure. In the embodiment shown in FIG. 13B, the two planar support elements are now perpendicular to one another, with the first edge 2401 of the first planar support element 2400 contacting the first face 2415 of the second support element 2410. Typically, the first face 2405 of the first planar support element would be flush with the first edge 2411 of the second planar support element in the second position. As with FIG. 13A, FIG. 13B could be a portion of foldable slide (e.g. with the side rail in use position with respect to the slide surface).

When moving from the first position (FIG. 13A) to the second position (FIG. 13B), the first hinge portion 2204 and second hinge portion 2206 may rotate toward one another, and in the second position may be contacting and parallel. The pivotal attachment element 2200 (shown in dashes in FIG. 13B) may be positioned between the first edge 2401 of the first planar support element 2400 and the first face 2415 of the second planar support element 2410. The first through-hole 2214 may (auto) align with the second through-hole 2216 as well as the receiving hole 2420 and/or a nut and/or a guide hole in the first planar support element (e.g., aligned with the first through-hole 2214). Then, a fastener may be attached from the receiving hole 2420 into a portion of the first edge 2401 of the first planar support element 2400. For example, a retained fastener may be used to attach and secure the first and second planar support elements, locking them into the second position (and such a locked/fixed position with the fastener extending into both planar support elements) might be termed a third position, as discussed below.

Referring now to FIGS. 14A-14C, a detailed view of the first planar support element 2400, the second planar support element 2410, and an assembly device comprising the pivotal attachment element 2200 and the fastener 2500 is shown. In the embodiment shown in FIGS. 14A-14C, the fastener may comprise a bolt 2500 (comprising a head 2512 and a threaded portion 2510) and a corresponding mating fastener locking element (e.g. a nut) 2504 may be used to attach the first planar support element 2400 to the second planar support element 2410, but in other embodiments, a different fastener and/or corresponding mating fastener locking element may be used. In FIGS. 14A-14C, a partial cut-away in shown (e.g., with outer surfaces removed to more clearly illustrate internal elements and how they interact in different positions).

FIG. 14A illustrates a first position, similar to the first position shown in FIG. 13A, where the planar support elements 2400 and 2410 may be parallel and the hinge portions 2204 and 2206 may be perpendicular. The fastener 2500 (e.g., a bolt) may be inserted into the receiving hole 2420, and may be held in position within the second planar support element (e.g., in the first position, pre-assembly, for example during shipment/storage) by the second through-hole 2216 (as described above) and/or a separate retaining element. In some embodiments, the first planar support element 2400 may comprise a pre-drilled hole 2502 configured to receive the fastener 2500. In some embodiments, the pre-drilled hole 2502 may also or instead comprise a nut 2504 (or other similar attachment element, for example a mating fastener locking element) configured to interface with the fastener 2500. In some embodiments, the mating fastener locking element may be integrated within the pivotal attachment element 2200. In an alternative embodiment, the fastener 2500 may thread directly into the material of the first planar support element via the pre-drilled (e.g., pilot/guide) hole. In some embodiments, the pre-drilled hole 2502 and/or mating fastener locking element may align with the first through-hole 2214 of the pivotal attachment element 2200 (e.g., with corresponding centerlines and/or sized to correspond with and/or mate with the fastener 2500).

The receiving hole 2420 may comprise a counter-drilled (or counter-bore, or counter-sink) section 2421 configured to fit the shape of the fastener 2500 and allow the fastener 2500 (e.g., the head 2512 of the fastener 2500) to be completely recessed within the thickness of the second planar support element 2410 (e.g., in the first and/or second positions). The countersink hole 2420, 2421 may pass through the second planar support element 2410 and/or retaining feature/element, so that the fastener 2500 is retained in the second planar support element 2410 pre-assembly. In some embodiments, the counter-drilled section 2421 may be at least as deep as the length of the threaded portion 2510 of the fastener 2500.

In some embodiments, the first edge 2401 of the first planar support element 2400 may comprise a recessed portion 2426 configured to fit the pivotal attachment element 2200, allowing the pivotal attachment element 2200 to be inset into the material of the first edge 2401. In some embodiments, the first face 2415 of the second planar support element 2410 may also comprise a recess portion, while in other embodiments, the recessed portion 2426 may be sized to fit the entire pivotal support element 2200 in the second position (shown in FIG. 14B).

FIG. 14B illustrates a second position, similar to the second position shown in FIG. 13B, where the planar support elements 2400 and 2410 may be perpendicular and the hinge portions 2204 and 2206 may be parallel. As shown in FIG. 14B, in some embodiments, the receiving hole 2420 may comprise a counter-drilled (or counter-bore, or counter-sink) section 2421 configured to fit the shape of the fastener 2500 and allow the fastener 2500 to be completely recessed within the thickness of the second planar support element 2410 (e.g., in the first and/or second positions).

FIG. 14C illustrates a third (e.g., secured) position (e.g., when the second position of the planar support elements has been locked/secured/fixed via the fastener extending through the second planar support element into the first planar support element, for example to provide rigid fixing attachment, for example by interaction with the mating fastener locking element), after the second position of FIG. 14B, where the fastener 2500 has been threaded into the pre-drilled hole 2502 (and/or the nut 2504 or other mating fastener locking element). In some embodiments, once the fastener 2500 has been threaded into the pre-drilled hole 2502, and the first planar support element 2400 is attached to the second planar support element 2410, a cap may be inserted into the receiving hole 2420 over the fastener 2500 covering the fastener (to provide a flush surface).

FIGS. 15-17 illustrate a foldable slide 300 in a first (flattened) position or configuration. FIG. 18 illustrates the foldable slide 300 in a second (assembled) position or configuration. The foldable slide 300 may be shipped or otherwise transported to the customer in the first (flattened position), wherein the flattened slide may be easier to transport, and then the customer may assemble the slide 300 by folding the portions of the slide into the second (assembled) position and securing the portions of the slide 300 (for example with bolts or other fasteners). The slide 300 may comprise two side rails 302 which may be mirrored and matching one another. The slide 300 may comprise a sliding surface 310 positioned between and attached to the two side rails 302. In some embodiments, the sliding surface 310 may be attached to the two side rails 302 via one or more hinge portions 320 (e.g. configured to allow folding of the side rails 302 with respect to the sliding surface 310, in order to provide the two configurations).

The side rails 302 may comprise one or more shaped portions configured to provide support and/or connection to other elements. For example, the side rails 302 may comprise panels 304 configured to extend beyond the sliding surface 310 and/or angled to connect to a play structure. The foldable slide 300 may also comprise an end stand 306 configured to support the slide 300 and contact the ground. The end stand 306 may be configured to extend beyond the sliding surface 310 and/or be angled to support the bottom of the slide above ground level. The main portion of the side rails 302 (e.g. between the panel 304 and the end stand 306) typically would be configured to extend longitudinally along the length of the slide, and for example might have a bottom surface similar to the slide contours.

In some embodiments, the sliding surface 310 may comprise one or more curved portions. For example, the sliding surface 310 may comprise a top curved portion 312 configured to provide a connection between the play structure (e.g., a floor of the play structure) and the sliding surface 310. In some embodiments, the top curved portion 312 may comprise a curve that approximately matches the shape of the panels 304. As another example, the sliding surface 310 may comprise a bottom curved portion 314 configured to curve approximately parallel to the ground from the sliding surface 310 when the slide 300 is installed for use. In some embodiments, the bottom curved position 314 may be attached to the sliding surface 310 via a hinge 315. In some embodiments, the bottom curved portion 314 may be attached to the end stand 306. In some embodiments, the bottom curved portion 314 may be attached to the end stand 306 via a hinge 322 that allows the end stand 306 to lay flat with respect to the rest of the slide 300 when the slide is in the first (flattened) position (shown in FIGS. 15-17) and allows the end stand 306 to be folded under the bottom curved portion 314 to support the slide 300 when the slide is in the second (assembled) position (shown in FIG. 18). In some embodiments, the end stand 306 may be attached to one or more stand rails 316 via one or more hinges 318, wherein the stand rails 316 are configured to fold with respect to the end stand 306 when the slide is in the second (assembled) position to create additional stability and strength for the end stand 306. Alternatively, the slide may comprise a flat end stand 306 with no stand rails 316.

The slide 300 may comprise one or more (and/or two long continuous) hinges 320 configured to allow the side rails 302 to rotate/fold with respect to the sliding surface 310. For example, the side rails 302 may be moved from a first position (shown in FIG. 17) to a second position (shown in FIG. 18) via movement of the hinges 320. In some embodiments, the hinges 320 may be incorporated into (and/or attached to) the sliding surface 310 and the side rails 302 during the molding process of the foldable slide 300.

In some embodiments, the hinge(s) 320 may comprise one or more (e.g., a plurality of) openings 334 configured to allow a bolt to pass through the side rail 302 and into the sliding surface 310 when the slide is in the second (assembled) position, wherein the bolt(s) may secure the side rails 302 into the second (assembled) position. In some embodiments, the hinges 320 may be similar to the hinge(s) 120 described above in FIGS. 6-7, comprising similar elements.

In some embodiments, the hinge 320 may comprise a through-hole 325 configured to receive and attach to a bolt that is passed through the opening 334 (for example, with full assembly requiring this type of fixing of the side rail in the second position with respect to the slide surface for all such hinges). As discussed above, in some embodiments, the corner joints/hinges (for example of a foldable slide structure) could employ/comprise a pivotal attachment element/hinge, which might be configured to retain a fastener and self-align the fastener for lock of the related corner panels when the slide is unfolded.

Referring to FIGS. 19 and 20, a detailed view of the end stand 306 is shown. FIG. 19 illustrates the foldable slide 300 in a first (flattened) position, and FIG. 20 illustrates the foldable slide 300 in a second (assembled) position or configuration. In some embodiments, the stand rails 316 may connect to (or otherwise interface with) the side rails 302 when the slide 300 in is the second (assembled) position.

FIGS. 21A-21B illustrate cross-sectional views of the folding steps for the end stand 306 and stand rails 316, wherein the stand rails 316 may be configured to rotate with respect to the end stand 306 about hinges 318 from a first (flattened) position shown in FIG. 21A to a second (assembled) position shown in FIG. 21B. In some embodiments, the stand rails 316 may be held in place in the second position by one or more attachment elements.

FIGS. 22A-22B illustrate cross-sectional views of the folding steps for the sliding surface 310 and side rails 302, wherein the side rails 302 may be configured to rotate with respect to the sliding surface 310 about hinges 320 from the first (flattened) position shown in FIG. 22A to the second (assembled) position shown in FIG. 22B. In some embodiments, the side rails 302 may be held in place in the second position by one or more attachment elements. For example, a bolt may be inserted into (and optionally held in place by) an opening 334, and then the bolt may attach to a through-hole 325. In the embodiment shown in FIGS. 22A-22B the opening 334 may be molded into the sliding surface 310 and the through-hole 325 may be molded into the side rail 302, as an example.

FIGS. 23-25 illustrate another embodiment of a foldable slide 400 in a first (flattened) position or configuration. FIG. 26 illustrates the foldable slide 400 in a second (assembled) position or configuration. The foldable slide 400 may be similar to the foldable slide 300, comprising similar elements and features, wherein the foldable slide 400 may comprise a separate end stand 406 that is not connected to the sliding surface 410 and/or curved portion 414 while the slide 400 is in the first position and may be attached to the sliding surface 410 and/or curved portion 414 while the slide 400 is in the second position.

The slide 400 may comprise side rails 402 attached to the sliding surface 410 and configured to rotate with respect to the sliding surface 410 about hinges 420. The slide 400 may comprise a top curved portion 412 and a bottom curved portion 414 attached to the sliding surface 410 via a hinge 415. The side rails 402 may comprise panels 404 configured to extend beyond the sliding surface 410 and/or angled to connect to a play structure.

In some embodiments, the hinge(s) 420 may comprise one or more (or a plurality of) openings 434 configured to allow a bolt to pass through the side rail 402 and into the sliding surface 410 when the slide is in the second (assembled) position, wherein the bolt(s) may secure the side rails 402 into the second (assembled) position. In some embodiments, the hinge 420 may comprise a through-hole 425 configured to receive and attach to a bolt that is passed through the opening 434 (for example, with full assembly requiring this type of fixing of the side rail in the second position with respect to the slide surface for all such hinges).

In some embodiments, the end stand 406 may be attached to one or more stand rails 416 via one or more hinges 418, wherein the stand rails 416 are configured to fold with respect to the end stand 406 when the slide is in the second (assembled) position to create additional stability and strength for the end stand 406. Alternatively, the slide may comprise a flat end stand 406 with no stand rails 416.

FIGS. 27A-27B illustrate cross-sectional views of the folding steps for the end stand 406 and stand rails 416, wherein the stand rails 416 may be configured to rotate with respect to the end stand 406 about hinges 418 from a first (flattened) position shown in FIG. 27A to a second (assembled) position shown in FIG. 27B. In some embodiments, the stand rails 416 may be held in place in the second position by one or more attachment elements.

Referring to FIG. 28, a detailed view of the end stand 406 is shown. In some embodiments, the stand rails 416 may connect to (or otherwise interface with) the side rails 402 when the slide 400 in is the second (assembled) position.

FIGS. 29 and 30 illustrate a detailed view of an opening 434 (wherein a slide 400 may comprise a plurality of openings about the hinge 420), wherein the opening is configured to allow a bolt 432 to be inserted into a through-hole 425 on the other side of the hinge 420. In some embodiments, the through-hole 425 may comprise a mating fastener locking element (such as a nut), corresponding to the bolt 432. In some embodiments, the opening 434 may be positioned adjacent to a retention well 440 configured to hold the bolt 432 in place in the opening when the slide 400 is in the first (flattened) position as shown in FIG. 30. Then, when the side rails 402 are rotated about the hinge 420, the bolt 432 may contact the through-hole 425 (and/or nut), and a user may be able to attach the bolt 432 to the through-hole 425, securing the slide 400 into the second (assembled) position, as described above.

Embodiments of the disclosure include systems, apparatuses, and methods relating to adjustable climbing surfaces, wherein a surface may be adjusted from a climbing wall to a ladder (and/or vice versa). In some embodiments, an adjustable climbing surface may comprise at least two positions which can be adjusted after installation. A user may also be able to adjust the climbing surface from a climbing wall to a ladder or steps (and back again). Climbing devices used within the consumer playset industry are fundamental in the way they are used as entry devices for swing sets and playsets. Embodiments of the disclosure include an innovative entry device (or climbing surface) that combines the functionality of a standard rung ladder and a rock wall, allowing a user the ability to easily switch therebetween.

For example, a climbing surface may comprise a plurality of adjustable slats, wherein the slats may be moved from a first position to a second position by a user. In the first position, the slats may be approximately vertical (relative to the ground and/or relative to a side bar) and may form a climbing wall. In some embodiments, one or more climbing rocks (e.g. hand and/or foot hold projections, which might be formed to resemble rock outcroppings) may be attached to the adjustable slats (so that when the slats are in the first position, they form a rock climbing wall with the rocks oriented facing outward). In the second position, at least a portion of the plurality of slats may be moved by the user to be approximately horizontal (relative to the ground and/or relative to a side bar) and may form a ladder (or step ladder, rung ladder stairs, or other climbing surface with steps). In the second position, the rocks attached to the slat(s) typically would face downward (e.g. be located on the underside) and the upper step/rung surface would typically be free of obstructions (e.g. a substantially flat plane forming an effective step run). In some embodiments, the adjustable slats may be rotated about a fixed point from the first position to the second position. In some embodiments, the adjustable slats may be rotated along one or more tracks from the first position to the second position. In some embodiments, the climbing surface may also comprise a locking mechanism, configured to (releasably/removably) lock the slats in the upright/first position for use as a secure climbing wall. Such a locking mechanism would typically be sufficiently secure and strong to support the weight of a user who might climb the wall, typically also including a safety factor.

In some embodiments, the adjustable climbing surface (which may also be called a combo climber and/or a shutter ladder) may comprise a left and right side rails that support the slats and provide housing for the mechanism and linkage that provides for the transformation from ladder to rock wall by simple operation of selection.

FIGS. 31 and 32 illustrate embodiments of an adjustable climbing surface 500 (which may also be called an adjustable climbing wall and ladder, and/or shutter ladder). The adjustable climbing surface 500 may comprise two side rails 502 and 504 (e.g., a left side rail 502 and a right side rail 504, and/or a first side rail 502 and a second side rail 504). The adjustable climbing surface 500 may also comprise a plurality of adjustable slats 510 (e.g. at least three adjustable slats, at least four adjustable slats, etc.) configured to attach to both of the side rails 502 and 504. In some embodiments, the adjustable slats 510 may rotationally or pivotally attach to one or both of the side rails 502 and 504 in such a manner as to allow for movement of the slats from the first to the second position (e.g. by pivot folding the slats).

In some embodiments, at least one of the side rails 502 and/or 504 may comprise one or more tracks 514 (e.g. a curved or arc-shaped slot) configured to interface with at least a portion of the adjustable slat(s) 510 (e.g. a projection or pin configured to slidably interface and interact with and project into or through the slot of the track). The track 514 may guide the adjustable slat 510 from a first position to a second position and/or from the second position to the first position, during movement therebetween. For example, in a first position (e.g., shown in FIG. 31), the adjustable slat 510 may be approximately vertical relative to the ground (when the adjustable climbing surface 500 is attached to a play structure) and/or relative to the side rail(s) 502 and 504. In other words, in the first position the slats are folded up to form a substantially vertical rock wall climbing surface, for example with all slats folded to form a single planar surface (with rock projections attached thereto). Then, in a second position (e.g., shown in FIG. 32), the adjustable slat 510 may be approximately horizontal relative to the ground (when the adjustable climbing surface 500 is attached to a play structure) and/or relative to the side rail(s) 502 and 504. In other words, in the second position the slats are folded down to form substantially horizontal (flat) steps or rungs, with the climbing rocks projections located on the underside so as to not interfere with the footing surface of the rung/step. In some embodiments, the track 514 may comprise end points (or stopping points) corresponding to the first position and/or the second position. Typically, the bottom/outer end point of the track slot would correspond to the second position, so that the track itself would securely hold the slat as a step in the second position by gravity pulling the interface of the slat downward against the bottom end point of the track.

In some embodiments, the first position shown in FIG. 31 may comprise a rock wall configuration, wherein the adjustable climbing surface 500 may comprise a plurality of climbing rocks 520 attached to the slats and facing outward (e.g. on the outer surface of the rockwall/slats), allowing a user to climb the adjustable climbing surface 500 as a rock wall. In some embodiments, the second position shown in FIG. 32 may comprise a ladder configuration, wherein the adjustable slats 510 may form a plurality of steps/rungs in a ladder (e.g. with the rocks 520 located on the underside to face downward). Typically, each adjustable slat might comprise one or more rocks 520 attached to the outer/underside surface of the slat, and the opposite side/face (e.g. the inner/upper or top side) of the slat would be approximately/substantially planar and flat (e.g. configured to provide an effective rung/step tread).

In some embodiments, the adjustable climbing surface 500 may comprise one or more stationary slats 512. For example, in FIGS. 31-32, every other slat would be stationary (e.g. with an adjustable slat therebetween). The stationary slats 512 may be fixed with respect to the side rails 502 and 504 and/or the adjustable slats 510. In some embodiments, the adjustable climbing surface 500 may comprise alternating stationary slats 512 and adjustable slats 510. Typically, those fixed/stationary slats would be oriented in the first position (e.g. vertically with climbing face/surface substantially parallel to that of the adjustable slats in first position). So typically, when all adjustable slats are in the first position, all of the adjustable and stationary slats would be substantially planar to form a single climbing wall surface. In some embodiments, the adjustable slats 510 may be sized to be an appropriate step depth (e.g. configured to provide effective step run) when in the ladder configuration (e.g., the second position, shown in FIG. 32). In some embodiments, the adjustable slats 510 may be sized to fit within the side rail 502 and 504 when the adjustable slat 510 is in the second position. In some embodiments, the stationary slats 512 may be sized to create an appropriate distance between the steps (adjustable slats 510) when in the second position. In some embodiments, the stationary slats 512 and adjustable slats 510 may be spaced apart to allow a hand to fit between a stationary slat 512 and an adjustable slat 510, particularly in the first position. In some embodiments, the stationary slats 512 and the adjustable slats 510 may comprise matching lengths (between the side rails 502 and 504). Typically, one or more of the stationary slats might also comprise one or more rocks 520.

In some embodiments, the adjustable slat 510 may be fixed by a pivot point at a bottom edge (e.g. when in the first position or inner edge in the second position) about which the adjustable slat 510 might pivot, wherein the top edge (in the first position, or outer edge in the second position) may rotate in an arc (along the track 514) from the first position to the second position. This configuration may allow for an open space (e.g. at least as large as the corresponding adjustable slat) above the adjustable slat 510 when the adjustable slat 510 is in the second position, allowing a user's foot to (partially) extend over the surface of the adjustable slat 510 (or step) if necessary.

FIGS. 33, 34, and 35 illustrate another embodiment of an adjustable climbing surface 600 (which may also be called an adjustable climbing wall and ladder, and/or shutter ladder). The adjustable climbing surface 600 may comprise two side rails 602 and 604 (e.g., a left side rail 602 and a right side rail 604, and/or a first side rail 602 and a second side rail 604). The adjustable climbing surface 600 may also comprise a plurality of adjustable slats 610 configured to attach to both of the side rails 602 and 604. In some embodiments, the adjustable slats 610 may rotationally or pivotally attach to one or both of the side rails 602 and 604.

In some embodiments, at least one of the side rails 602 and/or 604 may comprise one or more tracks 614 configured to interface with at least a portion of the adjustable slat(s) 610. In some embodiments, the adjustable slat 610 may comprise a peg 640 configured to attach to a top (in first position, or outer in second position) corner/edge of the adjustable slat 610 and configured to fit within and move within the track 614. The track 614 may guide the adjustable slat 610 from a first position to a second position and/or from the second position to the first position. For example, in a first position (e.g., shown in FIG. 34), the adjustable slat 610 may be approximately vertical relative to the ground (when the adjustable climbing surface 600 is attached to a play structure) and/or relative to the side rail(s) 602 and 604. Then, in a second position (e.g., shown in FIG. 35), the adjustable slat 610 may be approximately horizontal relative to the ground (when the adjustable climbing surface 600 is attached to a play structure) and/or relative to the side rail(s) 602 and 604. In some embodiments, the track 614 may comprise end points (or stopping points) corresponding to the first position and the second position, wherein the peg 640 may interface with the stopping points to prevent further movement of the adjustable slat 610. In other words, the track may interact with the adjustable slats to constrain the range of movement of the adjustable slats to a prescribed arc. Typically, the arc for each adjustable slat might span approximately 90 degrees.

In some embodiments, the first position shown in FIG. 33 may comprise a rock wall configuration, wherein the adjustable climbing surface 600 may comprise a plurality of climbing rocks 620 attached to the slats (e.g. on the outer surface in the first position), allowing a user to climb the adjustable climbing surface 600 as a rock wall. In some embodiments, the second position shown in FIG. 35 may comprise a ladder configuration, wherein the adjustable slats 610 may form a plurality of steps in a ladder (e.g. with an upper surface that is substantially flat and provides an effective step run or tread, and with the rocks located on the underside).

In some embodiments, the plurality of adjustable slats 610 may be connected via a connection system comprising a bar and a plurality of pivot joints, so that the adjustable slats 610 are configured to jointly move from the first position to the second position together, as a unit, where a user may only apply pressure to one of the adjustable slats 610 to move all of the adjustable slats 610. For example, each adjustable slat 610 may be attached to the side rail 602 (and/or 604) via a first pivot joint 636, wherein the first pivot joint 636 may pivot/turn with the adjustable slat 610. In some embodiments, the first pivot joint 636 may be attached to the bottom edge of the adjustable slat 610. In some embodiments, the first pivot joint 636 may be attached to a corner of the side edge of the adjustable slat 610, wherein the first pivot joint 636 and the peg 640 may be attached at opposite corners of the side edge of the adjustable slat 610.

The first pivot joint 636 may be attached to a pivot bar 632, wherein each adjustable slat 610 may be attached to a pivot bar 632 via a first pivot joint 636. The pivot bar 632 may also be connected to a second pivot joint 634, wherein the second pivot joint 634 may attach the pivot bar 632 to a connector bar 630. The connector bar 630 may extend along the length of the side rail 602 (or 604) (e.g. longitudinally) and may connect to each of the pivot bars 632 for each of the adjustable slats 610. Movement of the connector bar 630 may cause movement of all of the connected adjustable slats 610, for example, if pressure is applied to one adjustable slat 610, the movement of that adjustable slat 610 may cause movement of the connector bar 630 and subsequently movement of all of the adjustable slats 610 that are connected to the connector bar 630.

In some embodiments, the connector bar 630, pivot joints 634 and 636, and pivot bar 632 may be housed within the side rail 602 (which may fully enclose these mechanisms in a box-like structure). In some embodiments, a cover may be attached to the side rail to cover the connector bar 630, pivot joints 634 and 636, and pivot bar 632 as well as other internal elements. In some embodiments, the adjustable climbing surface 600 may comprise one connection system comprising the connector bar 630, pivot joints 634 and 636, and pivot bar 632 positioned within one of the side rails 602 or 604. In another embodiment, the adjustable climbing surface 600 may comprise two connection systems comprising the connector bar 630, pivot joints 634 and 636, and pivot bar 632 positioned within each of the side rails 602 and 604.

In some embodiments, the connection system may also comprise a locking mechanism configured to lock the adjustable slat(s) 610 in place relative to the side rails 602 and 604. For example, the locking mechanism may operate to lock the slats in the first (upward) position (e.g. configured for climbing wall). This locking may be accomplished in many ways, by locking any number of the following: one or more of the adjustable slats 610, the peg 640, the track 614, the pivot bar 632, and/or the connector bar 630. The locking mechanism may comprise a spring-loaded lock 650 that may be pulled or pushed by a user to engage and disengage the lock, allowing the adjustable slats 610 to be moved between the first and second positions. As an example, the side rail 602 may comprise a spring-loaded lock 650 comprising a fastener configured to be moved into and out of engagement with one or more holes 652 and 654 in the connector bar 630. For example, in the first position (shown in FIG. 34) the lock 650 may be engaged with the first hole 652. Then, to move the adjustable slats 610 into the second position, the lock 650 may be disengaged from the first hole 652, the slats 610 (and therefore the connecting mechanism) may be moved to the second position (shown in FIG. 35), and the lock 650 may be engaged with the second hole 654 to lock the slats 610 into the second position.

In some embodiments, the adjustable climbing surface 600 may comprise one or more stationary slats 612. The stationary slats 612 may be fixed with respect to the side rails 602 and 604 and/or the adjustable slats 610. In some embodiments, the adjustable climbing surface 600 may comprise alternating stationary slats 612 and adjustable slats 610. In some embodiments, the adjustable slats 610 may be sized to be an appropriate step depth when in the ladder configuration (e.g., the second position, shown in FIG. 32). In some embodiments, the adjustable slats 610 may be sized to fit within the side rail 602 and 604 when the adjustable slat 610 is in the second position. In some embodiments, the stationary slats 612 may be sized to create an appropriate distance between the steps (adjustable slats 610) when in the second position. In some embodiments, the stationary slats 612 and adjustable slats 610 may be spaced apart to allow a hand to fit between a stationary slat 612 and an adjustable slat 610, particularly in the first position. In some embodiments, the stationary slats 612 and the adjustable slats 610 may comprise matching lengths (between the side rails 602 and 604).

In some embodiments, the adjustable slat 610 may be fixed at a bottom edge, wherein the top edge may rotate (along the track 614) from the first position to the second position. This configuration may allow for an open space above the adjustable slat 610 when the adjustable slat 610 is in the second position, allowing a user's foot to (partially) extend over the surface of the adjustable slat 610 (or step) if necessary.

FIG. 36 illustrates yet another embodiment of the disclosure. The adjustable climbing surface 700 may comprise a plurality of adjustable slats 710 configured to rotate along tracks 714 with respect to one or more side rails 702 and 704. In some embodiments, the slats 710 may be connected via a connector bar 730. In some embodiments, the adjustable climbing surface 700 may comprise one or more climbing rocks 720. Some, but not all, adjustable and/or stationary slats may include climbing rocks.

Embodiments of the disclosure include systems, apparatuses, and methods relating to adjustable climbing surfaces, wherein a surface may comprise a plurality of climbing elements that may be easily attached, detached, moved, rearranged, or repositioned to create a plurality of configurations for the climbing surface. The climbing surface may comprise an innovative entry device that combines the functionality of a conventional rock wall climber along with the flexibility to create various climbing configurations that have varying degrees of difficulty (e.g. including step/ladder). The adjustable climbing surface may comprise one or more side rails that support and provide for slats that house adjustable climbing rocks and/or step pads, among other climbing elements. In some embodiments, a plurality of slots is spaced with a gap or slot therebetween, and the attachment of rocks, step pads, etc. may be within these gaps (to provide easy and quick reconfiguration) and/or in such a way as to effectively restrict rotational movement.

Climbing devices used within the consumer playset industry are fundamental in the way they are used as entry devices for swing sets and playsets. Embodiments of the disclosure include an innovative entry device (or climbing surface) that combines the functionality of any number of climbing surfaces due to the adjustable nature of all of the climbing elements, allowing a user the ability to easily switch between configurations.

For example, a climbing surface may comprise a plurality of (in some embodiment adjustable) slats, wherein a plurality of climbing elements may be attached to the slats via slots between the slats. In some embodiments, one or more climbing rocks (e.g. hand and/or foot hold projections, which might be formed to resemble rock outcroppings) may be attached to (e.g. between) the slats (to be fixed with regard to the climbing surface). In some embodiments, one or more step pads (e.g., forming a ladder or stairs shape on the climbing surface) may be attached to (e.g. between) the slats (to be fixed to the climbing surface). In some embodiments, one or more handles (e.g., for gripping by a user when climbing the climbing surface) may be attached to (e.g. between) the slats.

FIG. 37 illustrates an exemplary play structure 20 comprising an adjustable climbing surface 800 (set up for use, e.g. assembled) attached to a main structure. The adjustable climbing surface 800 may extend from a second (or higher) story (or floor) of the structure to the ground.

Referring to FIG. 38, the climbing surface 800 may comprise a plurality of climbing rocks 820, step pads 830, and/or handrails 840 that may be reconfigurable and/or adjustable (e.g. for easy attachment, removal, or repositioning). In other words, the climbing elements (e.g., the climbing rocks 820, the step pads 830, and/or the handrails 840) may be removably attached to the climbing surface 800. In the embodiment shown in FIG. 38, the adjustable climbing surface 800 may comprise a first configuration. The climbing surface 800 may comprise one or more (primarily vertical) side rails 802 and/or center rails 804. The climbing surface 800 may comprise a plurality of (primarily horizontal) slats 810 attached to the side rails 802 and/or center rail 804. The slats 810 may be positioned with slots/gaps 811 between each (vertically adjacent) pair of slats 810. The climbing surface 800 may comprise one or more spacers 812 positioned between the slats 810 configured to create the slots 811 (or spaces or gaps) between each pair of slats 810. In some embodiments, the spacers 812 may be attached to the side rails 802 and/or center rail 804. In some embodiments, the slots 811 would be too small for effective use as foot and/or hand holds, but in other embodiments some or all slots 811 might be sized to allow such use. The configuration of FIG. 38 has steps/ladder (with two handrails on either side) on one side and a rock wall on the other side.

FIG. 39 illustrates the adjustable climbing surface 800 in a second configuration, wherein the climbing rocks 820, step pads 830, and/or handrails 840 have been moved, removed, added and/or adjusted.

FIG. 40 illustrates the adjustable climbing surface 800 in a third configuration, wherein the climbing rocks 820, step pads 830, and/or handrails 840 have been moved, removed, added and/or adjusted. For example, FIG. 40 illustrates a configuration with steps/ladder (with one handrail) on one side and a rock wall on the other side.

FIG. 41 illustrates the adjustable climbing surface 800 in a fourth configuration, wherein the climbing rocks 820, step pads 830, and/or handrails 840 have been moved, removed, added and/or adjusted.

FIG. 42 illustrates the adjustable climbing surface 800 in a fifth configuration, wherein the climbing rocks 820, step pads 830, and/or handrails 840 have been moved, removed, added and/or adjusted.

FIG. 43 illustrates a detailed view of one or more climbing rocks 820 and step pads 830 attached to an adjustable climbing surface 800. In some embodiments, the climbing rocks 820 (and/or step pad(s) 830) may be secured in place relative to the slats 810 and/or slots 811 via a mounting wedge 822 (which typically is located on the opposite side of the slats/slots and projects through the slots 811 (often fitting snuggly within the slot 811)).

FIG. 44 illustrates an exploded view of the adjustable climbing surface 800. As described above, the climbing surface 800 may comprise a plurality of slats 810 separated by slots 811 (or spaces), wherein the slots 811 between the slats 810 may be created by spacers 812, and wherein the spacers 812 hold the slats in place relative to the side rails 820 and/or center rail 804. In the embodiment shown in FIG. 44, the spacers 812 may be attached to (or formed on, or molded onto) a spacer rod 813, wherein one or more spacer rod 813 may be attached to the side rails 802 and/or center rail 804. In the embodiment shown in FIG. 44, a spacer rod 813 is positioned on each of the two side rails 802 and the center rail 804, however in other embodiments only one spacer rod 813 may be used. In an alternative embodiments, the spacers 812 may be individually positioned between the slats 810, without the use of a spacer rod 813 to connect the spacers 812. In some embodiments, the slats 810 may be positioned against (or within) the spacers 812, and then fasteners 814 may be used to attach the slat 810 and spacer 812 (or spacer rod 813) to the side rail(s) 802 and/or center rail 804. In the embodiment shown in FIG. 44, screws 814 are to attach the slat 810 and spacer 812 (or spacer rod 813) to the side rail(s) 802 and/or center rail 804. Alternatively, the spacers 812 (or spacer rod 813) may be attached to the side rail(s) 802 and/or center rail 804 before the slat(s) 810 are fitted with the spacer(s) 812, and the slats 810 may be attach to the side rail(s) 802 and/or center rail 804 independently of the spacers 812 (or spacer rod 813). Other embodiments could attach the slats 810 directly to the side/center rails (e.g. without spacers), with positioning of the slat attachment forming the slots 811.

FIG. 45 illustrates a detailed, assembled view of the side rail 802, spacers 812, spacer rod 813, slats 810, and screws 814 described above in FIG. 44.

Referring to FIG. 46, a climbing rock 820 may be attached to a climbing surface 800 using a T-shaped mounting wedge 822, wherein the mounting wedge 822 may be shaped to fit within the slot 811 between two slats 810 (e.g. a portion of the wedge fits snuggly within the corresponding slot 811 and the other portion is larger than the slot 811 to act as a flange or shoulder for clamp attachment). The climbing rock 820 may be attached to the mounting wedge 822 using one or more fasteners 824. In the embodiment shown in FIG. 46, two bolts 824 are used to attach the climbing rock 820 to the mounting wedge 822 to prevent unwanted rotation of the climbing rock 820 when it is installed for use. In this example, the mounting wedge 822 may be long enough to span two fastener openings in the climbing rock 820, and both fasteners 824 may attach to the mounting wedge 822 (e.g. the fasteners would pass through the wedge, through the slot 811, and into or through the rock/step). Typically, either the wedge or the rock/step would have holes with matching threads (e.g. to secure the fastener).

The mounting wedge 822 may allow the climbing rock 820 to be adjustably and removably attached to the climbing surface 800, to allow for rearranging of the climbing rock 820 (e.g., into the different configurations shown in FIGS. 38-43) without having to drill or have pre-drilled holes in the slats. In some embodiments, the fasteners 824 may be completely removed from the mounting wedge 822 to allow for repositioning of the climbing rock 820. In some embodiments, the fasteners 824 may be loosened but not completely removed, and the climbing rock 820 and mounting wedge 822 can be slid along the slot 811 to another (horizontal) location, and re-tightened.

Referring to FIG. 47, a step pad 830 may be attached to a climbing surface 800 using a one or more T-shaped mounting wedge 832, wherein the mounting wedge(s) 832 may be shaped to fit within the slot 811 between two slats 810. The step pad 830 may be attached to the mounting wedge(s) 832 using one or more fasteners 834. In the embodiment shown in FIG. 47, two bolts 834 are used to attach the step pad 830 to the mounting wedge(s) 832 to prevent unwanted rotation of the step pad 830 when it is installed for use. In the embodiment shown in FIG. 47, two mounting wedges 832 are used to attach the step pad 830 to the climbing surface 800, while in other embodiments, a single mounting wedge 832 may be used.

The mounting wedge(s) 832 may allow the step pad 830 to be adjustably and removably attached to the climbing surface 800, to allow for rearranging of the step pad 830 (e.g., into the different configurations shown in FIGS. 38-43). In some embodiments, the fasteners 834 may be completely removed from the mounting wedge(s) 832 to allow for repositioning of the step pad 830. In some embodiments, the fasteners 834 may be loosened but not completely removed, and the step pad 830 and mounting wedge(s) 832 can be slid (horizontally) along the slot 811 to another location, and re-tightened.

In some embodiments, the mounting wedge 822 comprises a wide portion 821 (configured to fit behind the slot 811 and serve as a shoulder or flange) and a narrow portion 823 (configured to fit (snuggly) within the slot 811, e.g. with a height corresponding to that of the slot 811). In some embodiments, the narrow portion 823 fits within the slot 811, and the wide portion 821 braces against the (rear surface or backside of the) slats 810 on either side of the slot 811.

In some embodiments, the fastener passes through the rock, through the slot, and into or through the wedge (and if it passes through the wedge, it would typically require a nut to secure, while if it passes into the wedge then the wedge typically has holes with matching threads to allow for secure attachment).

In some embodiments, the mounting wedge 832 may be positioned on a back side of a slot and the step pad 830 may be positioned on a front side of the slot, with a portion of two slats (not shown) held between the step pad 830 and the mounting wedge 832 when assembled. The mounting wedge 832 may comprise a wide portion 831 (configured to fit behind the slot 811) and a narrow portion 833 (configured to fit within the slot 811). The step 830 comprises threaded holes corresponding to the fasteners 834, to allow the fasteners to be securely screwed into the step to clamp the step onto the slats.

In some embodiments, the mounting wedge 822 may be positioned on a back side of a slot and the climbing rock 820 may be positioned on a front side of the slot, with a portion of two slats held between the climbing rock 820 and the mounting wedge 822 when assembled. The mounting wedge 822 may comprise a wide portion 821 (configured to fit behind the slot 811) and a narrow portion 823 (configured to fit within the slot 811).
